Hi... we are still talking about proxy :). Now, we want to play Skype and we have to set proxy first. This how-to has been tested in Ubuntu Maverick Meerkat. Here we go:
# When you launch Skype, you will get icon in your top-right panel
# Right click it and choose Options
# Change proxy ip address, username, and password as appropriate (click image to enlarge)
We are done here :). Enjoy!
